\#Webpage Design Dimensions and Their Measurement Items 

A participant only scored webpages on a single dimension. No additional instruction was given, besides the brief instruction (see _Pre Rating Instructions.png_) shown before scoring trials to all participants for all dimensions (an example of a rating scale depended on the rated dimension). A 7-point measurement scale was always shown at the bottom of a page.
